Genes affected

ENSG00000241489 (HGNC:):

IDS (HGNC:5389): (iduronate 2-sulfatase) This gene encodes a member of the sulfatase family of proteins. The encoded preproprotein is proteolytically processed to generate two polypeptide chains. This enzyme is involved in the lysosomal degradation of heparan sulfate and dermatan sulfate. Mutations in this gene are associated with the X-linked lysosomal storage disease mucopolysaccharidosis type II, also known as Hunter syndrome. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed. [provided by RefSeq, Jan 2016]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.58).

Variant summary: The IDS c.438C>T (p.Thr146Thr) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. 5/5 splice prediction tools predict no significant impact on normal splicing. This variant was found in 24360/87524 control chromosomes (including 2605 homozygotes and 9302 hemizygotes) at a frequency of 0.2783237, which is approximately 96 times the estimated maximal expected allele frequency of a pathogenic IDS variant (0.0028868). Thus this variant is a common polymorphism found in the general population. In addition, multiple clinical diagnostic laboratories have classified this variant as benign and the variant is considered a common polymorphism in the literature. Taken together, this variant is classified as Benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
